Optical manipulation of vibration amplitude of electrostatically actuated cantilevered M0S2

摘要

Transition metal dichalcogenide such as MoS2; is expected as high performance nano-electro-mechanical devices due to their unique electrical, optical and mechanical properties. One can expect that the combination of these properties are efficient to develop the novel functional devices. Here, we demonstrates the amplitude control of resonance characteristics of a cantilevered MoS2; on the planar substrate, which is actuated by electrostatically. The AC and DC bias voltage dependences of the vibration amplitudes are well explained by the simplified model under linear elastic regime. Moreover, we demonstrate the optical manipulation of the vibration amplitude at the resonance. Under the irradiation of strongly absorbed light by MoS2:, the vibration amplitude is successfully manipulated by the laser intensity change.
